Introduction

Trade value over the years

Note:

• The y axis is in log scale, so instead of a
  1, 2, 3… progression expect a
  1, 10, 100… progression
• The data from the point where the export value substantially increases is missing, which is data of 2013.

Number of trades with high value

Note:

• The trades of value $0 signify represent years where there was no trade value recorded

Import vs Export over the years

Note:

• The imports values were way higher in the earlier years as compared to recently, which i think is a good sign
• The exports values are moving in the opposite direction, which is also a good thing

The cost of producing coal has gone up over the years

.. and so has the value

These two variables showed a high correlation of 0.7358699 throughout the years
